Thus, the outlet B," indicate `they` more readily inducing when required, perfect combustion, and complete ventilation, by alifoiding or. supplying the requiredv amount of oxygen, throughout the whole volume of lire. Thus it is, that this apparatus is a certain remedy against the smoke' ing of defective chimney tlues, or iire draft. The main volume of cold air may be tsupplied to the perforated blower pipe, by any of the well known methods .of pipes, or tubes carriedbeneath the licor,v or in' any other well known mode, none of which however do we claim.

The back of this fire place, w, fw, w, to, fits flush up to the back of ythe recess fc, 50,' but there is a suitable space between, the tops, and sides of the casing and lire place, as at y, jij, a, a. Within the bottom part of the recess or casing fr, a, an, x, is fitted a detachable ash or cinder box e, e, e, e, half the length of the whole recess. The top, not projecting above the| level of the hearth stone oi front of fire place. This box is set in the middle, of the lire place, and at each end thereof, and flush thereagainst, is arranged a distinct box, or water chest S, S, S, S. Thus the whole s ace from side to side of the recess, is fille up, by the boxes S, S, S, S and ash pan or box e, e, e, e. Through the ends of the ash box or pan, and the ends of the water chests S, S, S, S, opposite' to each other are holes, or communications D, l), Fig. 3, into which are ing one in the pipe Fig. 8. The ends of lthis y pipe are supported by rests o, o, Fig. 3, attac-hed to the inside of the ends of the ash box.

Through the front ofl this box; e, e, e, e, is a suitable sized hole of .about` one or two inches into which is fitted, the

shoulder of collar arm g", Figs. 3 and 9.;

This shoulder 'or arm, extends through, and! lits into an air pipe or draft tubecx. This? tube has a revolving valve or cut 0E, with;

rod running upward, having a head or capc,

fitting into a counter sink, formed in' th'e hearth stone, as at b, c, Fig.l 1. Attached to the outside o-f the lire place, about mid-z way more or less, are diaphragme, parti-` tions or shelves 85, &, which divide the spaces y a, y, Fig. 2. Thus forming hot air or vapor chambers, and reserviors or gas receivers. These shelves 'or partitions each have two holes, A, A, B, B; into one each of which is iitted,`vertically -arrangedv smoke or conduit pipes, L, L, of' from 1', to 2,A inches diameter, passing down parallel, with pipe,by passing through the ends of the wavter chests S, S, S, S, S, S, S, S, and the ash panor ycinde'r LboXJe, e, 6,6'. The arms of these pipes, each have one or more branches, or elbows, turned downward, with open ends, and dip-into the water chests as aty g r, gag-g 7, go", Fig. 3. Thevbranches 1yr, fr, r, dip down into the water about half an inch, or only sufficiently deep to admit of as little pressure of the water as possible, in order to admit of the passing of thelcarbonaceous matter and, smoke, through the volume of water in the chests S, S, S, S.

In order to obviate any undue accumulation of carbonaceous matter within the recesses or reservoirs e, a, e, a, provision is made thereF for by using the valves or shut oifs t, h, at tached to the shifting or adjusting rods t :t

which valves, together with the valves J* Jl,may be opened so as to afford the passage of the excess of matter immediately through the perforated blower pipe or tube, out, and into the coals, or flame of the fire, to be consumed, or passed olf, up, through, and out of the neck, or flue of thechimney.

The ends, of the fire place sides fw, fw, fw, w, may extend entirely down to the bottom of the water chests s, s, s, s, s, s, and in suoli case they must be perforated above the water line, or their ends may not touch the water, either -of which, will admit of the purified gaseous matter, to enter and occupy the spaces, o-rreceivers, y, y, Fig. 3. In the construction of our economical lire place, it can be so arranged, as to admit of converting the smoke reservoirs e, e, e, e, into gas receivers also. Y

The process. of imperfect combustion which we avail ourselves of, to produce gas, is brought about by closing up the front of the fire place, by a fire board or an attachable shield plate, door, or equivalent. The shutting off, of the common atmosphere of the room, together with almost entirely cutting off, or vat least greatly diminishing the draft of cold air, afforded by the air tube or pipe Cf, together with turning down, or adjusting the blowerpipe, and also shutting down the valve or damper m, Fig. 3, thus aording a limited amount of draft, and oxygen, imperfect combustion is the consequence, and the product thereof, instead of being permitted to escape, upward, out of 'the chimney and belost, is diverted in its e, a, a, and thence passes down through the conduit pipes L, L', induced by the pressure, and accumulation of the carbonaceous gas, in

. the `fire place. `1And thus` this carbonaceous Inatter affordedwby"iinperfeet combustion is causedto beinjectedinto, and through the `[watercontainedyinuthechests .s, "is, .3', and water contained in itliegchests S, S, S, S, and assumes thenatureof an `inflammable mate, lter." In the forming of this inflammable article, thewvalves JH "1*, Fig. 3must `be "shutdown overftheholes A,A, and the "whole,apparatuscontaining the gas, must be airtight.` Thereceivfers, or the Vinant-lepiece rnaybetapped, `or `colnmunicated with by 3 `tuloes, pipes, orthe ordinary gasttings, and

`distributed throughoutpany dwelling.

M l `Having "describedthe construction, nature l l and ".priciples of :our :improved economical Viire place; what" we claim as new, useful, l andof our invention, and desire to secure by ""Letters Patent Vof the United States, is as fo1lows,t`fiz:

claim the adjustable perforated blower pipe with perforated collar, as described; arranged with the detachable, fire `place the latter having aperforated throat ianddouble funnel Ventilator; together with the valves, diaphragms partitionsysmoke conduit pipes, as constructed and arranged with the recess casings, forming airchambers, and` gas receiving apartments, substantially as described and shown, and for the purposes set forth.
